Module not found error

[u7068758]

Hi,
Although cogent3 has been successfully installed as shown below.
But when I try to perform dot plot in JupyterLab it gives the error: “No module named cogent3” (screenshot shown below)
Can you please guide me what’s the issue and how to solve?

Hi @u7068758,

From the first screenshot showing terminal output from pip install it looks like you are running a conda environment. From this and the second screen grab (showing JupyterLab) I'm guessing the error is because JupyterLab is not connected to that conda environment. So I have a few questions, the answers to which will help us pin this down.

1. What version of Windows?
2. Are you running conda within the Windows Subsystem for Linux (WSL)?
3. How did you install JupyterLab?

I'm using windows 10. Firstly, I installed Miniconda and then launched JupyterLab from Anaconda Navigator. Then I installed JupyterLab using the command "pip install JupyterLab" using command prompt App. The end result is as below:

I don't have a Windows machine, so I can't check this myself. Let me know if it works, or not!

First, quit JupyterLab. Then, in the terminal make sure the conda environment is active and install ipykernel using pip

$ pip install ipykernel

then create a kernel (this is a program that communicates between Python and JupyterLab)

$ python -m ipykernel install --sys-prefix --name python3 --display-name python3

When that's done, in the terminal start JupyterLab

$ jupyter lab

In a new Jupyer notebook try

import cogent3

I tried this way. The error persists (screenshot shown below). What do you mean when you say to use the command line launcher?

[u7068758]

Sorry, I wrote cogent instead of cogent3 let me try again.

[u7068758]

Error persists.

$ jupyter lab
